Tire tread



FIG. 1 is a perspective view of the tire tread;

FIG. 2 is an elevational view thereof;

FIG. 3 is a left side view thereof; a right side view thereof is a mirror image of the left side view; and,

FIG. 4 is an enlarged fragmentary view from A-A to A′-A′ in FIG. 2, showing the details of the tire tread.

The regular broken lines are used to show unclaimed environment, and thus form no part of the claimed design. The alternating short and long broken lines define the enlarged fragmentary area only and form no part of the claimed design.

The outside portions of the cylindrical surface of the tire tread repeat the design illustrated in FIGS. 1 and 2 and thus the front, back, top and bottom plan views thereof are identical thereto.

The regular broken lines are used to show unclaimed environment of the side of a tire, and thus form no part of the tire tread claimed herein.

The alternating short and long broken lines define the enlarged fragmentary area illustrated in FIG. 4 and form no part of the tire tread claimed herein. 

CLAIM The ornamental design for a tire tread, as shown and described.
